If I could give zero stars I would. Avoid this company like the plague, for your own sake. Had a new door in Feb 2025, which developed a leak. To be fair they did attend twice this year, once to tighten the locking mechanism to try to get a better seal to stop the rain entering the property, this failed. 2nd visit same engineer said that the frame was bowed and needed replacing and also said that he felt the aluminum bar between the door and side glass panel may not have been fitted, and he would check at head office to see the original order and then return to check measurements. That was 19th February. Since then we have been calling and emailing to get an update and each time no answer - goes straight to answerphone. Messages left for an update each time but still no response. Door is still leaking and still no response! I have even message Britannia using their WhatsApp messaging service and used their Facebook but no responses. We have a 10 year warranty which is not worth the paper it is written on!!

Multiple problems from the start so strap in. The job was 16 windows, three French doors and front and back doors. The follow-on job is the rear of the house with 14 more windows, a 3m bifold and a 2m bifold doors. I was told that if I paid the deposit in Nov 25, the installation would be before Christmas because that was their quiet time. That was not true and not achievable. It took weeks for them to get the spec right from small details like hinge colours to French doors and windows missed of entirely. I had to go through the spec multiple times to get it right and corrected mistakes seemed to reappear. The pictures in the spec didn’t always match the description because of issues with the software. I had to chase to get the surveyor booked because they forgot to book the appointment. Surveyor laughed at the Christmas install date. I had specified a dog flap in the back door which the sales guy said would be fitted. This was incorrect, I had to supply it. Surveyor said mid Jan for some of the windows and mid Feb for the doors. Couldn’t get hold of anyone throughout Dec either phone or email and feared they’d gone bust. Finally had someone show up and he got on with it OK but was missing various trim for windows and French doors. There was the wrong window handles on one window. Wrong locks on the French doors. One of the panes of glass was the wrong size so he put a piece of plastic in its place temporarily. He came back to fit the pane but brought the wrong size again. We’re in April and it’s still not done from Jan and no indication of when it will be done. They sent the final invoice when there were still three doors and three windows left to install. They fitted the front door mid Feb, still waiting for it to be finished. He was supposed to fit the back door the same time, but he couldn't find it in the factory. He was booked in to fit it but didn’t show up. He arrived a week late because he had been double booked. I had to ask where he was when he didn’t show. When the back door finally arrived, it was the wrong colour. There were so many errors on the spec, I missed this one, so they won’t even talk about it. He had to fit it because the old door had been ripped out. Either way, it’s still not finished and it wouldn’t open. They sent a subcontractor to fix the door so that it actually opens without kicking it. Debris left on site since Jan. Here’s the big one; the building inspector has said the upstairs windows do not comply with fire regulations. Launa’s reaction was that I should have “satisfied myself that they were compliant before they were fitted”!! They have offered a bodged solution. I don’t know where to turn to now.
